Usnic and ALA

If I was to do a cycle (or a couple of cycles, doesn't matter) of usnic acid, I'd choose my "extra" as ALA, among other things (Vit. C, etc.). My question is, though, that given that R-ALA is more effective than ALA, at least concerning insulin-mimicking, is it an equally more effective antioxidant? Assuming that R-ALA is something like 3 times more effective (I say that because the dosage of R-ALA compared to that of ALA is usually a third...at least from what I've read), if it were beneficial to take X amount of ALA a day while on a UA cycle, could I take 1/3X amount of R-ALA?
